Is it possible to have a triangle with two acute exterior angles?

No.
In any triangle on a plane surface, each exterior angle is equal to the sum of the other two interior angles.
Suppose A,B and C are the interior angles and a b and c the corresponding exterior angles.
Then a < 90 implies that B + C < 90
and b< 90 implies that A + C < 90
This gives B+C+A+C < 180 so that A+B+C < 180 which contradicts a property of triangles.

A triangle that has three 3 acute angles is a what?
A triangle with 3 acute angles is an acute triangle. All the angles in an acute triangle are acute.
What shape has two acute angles?
There are many possible shapes with two acute angles.
How many acute angles are in an acute triangle?
In an acute triangle, all three angles are acute.
How many acute angles are in a acute triangle?
there are three acute angles in an acute triangle, because there are three corners.
Can a triangle be acute and isosceles?
Yes, that's possible. For instance a triangle with the angles 70°, 70° and 40° is both acute and isosceles.
Is it possible for some triangles to have none exterior angle obtuse angle?
Yes, a Triangle can have 3 obtuse EXTERIOR angles of measure 120° ONLY in the case of an equilateral Triangle. OTHERWISE, a Triangle always has 2 obtuse Exterior angles and 1 acute Exterior angle.
Why is it possible for an isosceles triangle to be an acute explain?
It is possible for an isosceles triangle to be an acute triangle because, in an acute triangle all the angles have to be less than 90o.
What is the least number of angles an acute triangle can have?
All acute triangles have 3 interior angles and 3 exterior angles. This is true for all triangles.
A triangle that has three 3 acute angles is a what?
A triangle with 3 acute angles is an acute triangle. All the angles in an acute triangle are acute.
Is it possible for a triangle to have 3 acute angles?
Yes
Is it possible to have a triangle with three acute angles?
yes it is
Can a pen for a horse be acute right triangle is it possible?
In any right triangle, the two angles at either end of the hypotenuse are both always acute angles. But I don't think that would be called an 'acute' triangle, because an acute triangle is one in which all three angles are acute ones.
What is the least number of acute angles that a triangle have?
Every triangle must have either 2 or else 3 acute angles. The least possible is 2.
Is a triangle with two acute angles possible?
yes.. isosceles
What is the largest possible acute angle in a right triangle?
A right triangle is a triangle with one of its angles being 90o. The requirements for the other two angles are that they both be acute and total to 90o. Therefore, the largest possible acute angle in a right triangle is 89.99999...o.
What shape has two acute angles?
There are many possible shapes with two acute angles.
How many acute angles are in an acute triangle?
In an acute triangle, all three angles are acute.
